Query: NC_003413:128228 Pyrococcus furiosus DSM 3638, complete genome
Lineage: Pyrococcus furiosus; Pyrococcus; Thermococcaceae; Thermococcales; Euryarchaeota; Archaea
General Information: This strain was isolated from a shallow marine solfataric (volcanic area that gives off sulfuric gases) region at Vulcano Island, Italy. This organism is a strictly anaerobic, hyperthermophilic archaeon. Growth occurs at temperatures between 67 and 103 degrees C, with optimal growth at 100 degrees C and a pH of 7.0. This organism is highly motile due to a bundle of flagella.
Subject: NC_020134:845164 Clostridium stercorarium subsp. stercorarium DSM 8532, complete
Lineage: Clostridium stercorarium; Clostridium; unclassified Ruminococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: Lignocellulosic biomass has great potential as an abundant and renewable source of fermentable sugars through enzymic saccharification. Clostridium stercorarium is a catabolically versatile bacterium producing a wide range of hydrolases for degradation of biomass. Together with Clostridium thermocellum, Clostridium aldrichii and other cellulose degraders, it forms group I of the clostridia. It is moderately thermophilic, with an optimum growth temperature of 65 degrees C, and has repeatedly been isolated from self-heated compost. The two-component cellulase system of C. stercorarium has been investigated thoroughly. Due to its ability to utilize the various polysaccharides present in biomass it is especially suited for the fermentation of hemicellulose to organic solvents. Some isolates have been used in Japan in a single-step ethanol-fermenting pilot-process with lignocellulosic biomass as substrate.
